| Abstract | Bridges are highly investment structures and an important landmark in any country. Besides being vital links in transportation system, strength, safety and economy are the three key features that cannot be neglected, before finalization of types of bridges, the responsibility of structural engineer is to take care of financial requirements and site conditions also. The paper presents the optimal span of steel composite girder bridges for Expressways. It deals with economy of steel plate girder bridge of conventional shape. To investigate an economy, it is proposed to innovate the shape of steel plate girder bridge. Optimization of innovative shape of plate girder bridge is by selecting various parameters with constant optimum web depth and balanced span arrangements. Plate girder bridge design is carried out by selecting different parameters. These parameters are: span- 25 m to 50 m, and number of girder – 3, 4 and 5 girders. The structural optimization is performed by the parametric study approach and plot graphs and curves to observe the effects of such parameters on the span of the bridge. |
